SWINGING HOT-SAW FOR ROLLING-MILLS.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed January 3, 1910. Serial No. 536,189.

To all whom it may concern:

Be it known that I, AUeUsT WILHELM SrARon, engineer, subject of the Kingof Sweden, residing at Skolgatan 14:, at Skofde, in the Kingdom ofSweden, have invented certain new and useful Improvements in SwingingHot-Saws for Rolling-Mills, of

- which the following is a specification.

is a vertical section after the line A--B in I Fig. 1.

On a shaft 10, which turns in bearings on the supports 9, is a pendulumarm 1, hanging. To the lower end of said arm is an electric motor 2fastened, especially designed for this purpose. One end of the motorshaft carries the circular saw 3, and the other end carries a flywheel 4in order to partly balance the uneven load. The regulation of themovements of the saw against and from the work is done with the handle 5which is fastened on the rock shaft 6, and the motion is transmitted tothe swinging arm 1, carrying the motor and the saw through arms 7fastened on the same shaft and further through the links 8, connectingsaid arms with the ends of the motor. The

handle 5 is provided with a suitable locking arrangement, as for examplea spring latch 11, which catches into notches on a segment 12. With thisarrangement, the motor with the saw can be put in any desired sideposition before the sawing. The regulation can also be done in someother way. Especially for saws of larger sizes it might be necessary touse a separate motor with gearing arrangement, a steamor hydrauliccylinder, etc.

13 is a guard.

As the saw is directly coupled to the motor shaft, belting isunnecessary, and hereby not only a great disadvantage, connected withother swinging saws, is removed, but also the working expenses have beenconsiderably reduced. A swinging saw of the present design willtherefore, not only in manufacturing but also in working expenses bemuch cheaper than any other swing saw of the same capacity.

Having thus described my invention, I declare, that what I claim is Inswinging hot saws for rolling mills, the combination with a pendulumframe, of an electric motor supported in the lower end of said frame, acircular saw directly mounted on the rotating shaft of said motor, meansfor swinging said frame, said means consisting of arms mounted on ashaft and controlled by a handle, and links at both ends of the motorconnected to said arms and to said frame.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

AUGUST WILHELM STARCK.
